m82 galaxy

A line drawn through three stars in the sp [south preceding, SW] to a fourth in the nf [north following, NE] passes directly through the nebula. Throughout the galaxy’s center, young stars are being born 10 times faster than they are inside our entire Milky Way Galaxy. On 21 January at M82 lies at an estimated distance of 12 million light years. Book Category Commons Portal.

When star formation becomes too vigorous, it will consume or destroy the material needed to make more stars.

Bode, on December galwxy,and by M. Become a member of The Planetary Society and together we will create the future of space exploration. Retrieved 14 April It is very long, narrow, and bright, especially at its northern limb, but rather paler than No. There have been several theories about the nature of this object, but currently no theory entirely fits the observed data.

Located 12 million light-years away, M82 appears high in the northern spring sky in the direction of the constellation Ursa Major, the Great Bear. The resulting huge concentration of young stars carved into the gas and dust at the galaxy’s center.


We find that these young stellar clusters have inferred masses and sizes comparable to globular clusters. A suggestion to explain those features is that M82 was previously a low surface brightness galaxy where star formation was triggered due to interactions with its giant neighbor. In spite of its inclusion in the Messier Catalogthis peculiar galaxy was actually discovered by J. In Aprilradio astronomers working at the Jodrell Bank Observatory of the University of Manchester in the UK yalaxy an object in M82 that had started sending out radio gallaxy, and whose emission did not look like anything seen anywhere in the universe before.

M82, the Cigar Galaxy

Retrieved 15 December These arms emanate from the ends of the NIR bar and can be followed for the length of 3 disc scales. Recently, over new, young globular clusters have been discovered with the Hubble Space Telescope.

The unusual radio transient in M Astronomers assembled this six-image composite mosaic by combining exposures taken with four colored filters that capture starlight from visible and infrared wavelengths as well as the light from the glowing hydrogen filaments.


In other projects Wikimedia Commons. M82 was previously believed to be an irregular galaxy. Bright M82 is fairly easy to find — once you catch on to a certain trick. Throughout the galaxy’s center, young stars are being born 10 times faster than they j82 inside our entire Milky Way Galaxy. The excitation of the ionized gas indicates an average effective temperature for the OB stars of 37, K, with little spatial gaalxy across the starburst regions.

Most of the pale, white objects sprinkled around the body of M82 that look like fuzzy stars are actually individual galaxh clusters about 20 light-years across and contain up to a million stars. Massachusetts Institute of Technology. Phi, is pronounced to be double, both companions being of the 5th magnitude, and only half a second asunder. Even though the arms were detected in NIR images, they are bluer than the disk.
